Default Arrma Limitless 1/7 Drag Build Help Please ?

Hi

I have three Limitless.
I would like to build one of them to Drag.
And have the other for Speedruns and one for allround street bashing.

I have never build a DRAG Car before.
What do i need to do this ?
Important and good to know things ?

I run them all 8s.
In Drag you maybe want less Cells ?
Less weight ?
Foam wheels ? Or soft rubber slicks like GRP Rain ?
What tyre sauce you need if you use Foam at asphalt ? I have seen 4 different colors tyre sauce at my local shop. What is for asphalt outdoor use in drag ?
I dont need indoor carpet sauce

I have MAX 6 ESC, is that ok ? or do i need Castle ?
I know that Castle are great for speedruns. Drag maybe MAX 6 is enough ?

What motor would be good ? I have HW 4985 6s 1650kv and 4985 8S 1250kv Spektrum

Gearing ?

Spool at front diff ? Heavy oil rear ?
I have both Spool and also one Center diff 46t.
Center diff maybe should be 46t ? Spool or 2million oil in center ?

i have V1 Limitless

Im thinking top speed about 50mph is enough.
Need get there fast as possible without do anything insane.
Just random great Drag set up to have fun.

I have many 4s and 6s white china hobby line lipos with 8mm bullet connectors
i can do 4s. 6s. 8s with these
6200-9500mah

Please help me out with this.
